I've been working on a character rigging script. There's a lot of great work out there, and I am trying to learn to impliment some of the features I've seen. When it is finished, I intend to release the rigging scripts for free so that anyone can place point helpers and create rigs for their own characters. This rig was created using my rig script.

Feedback and advice would be really helpful. It is not ready for production yet. Use at your own risk.
